I would usually say no but so many sites seem to link to that same page they are viewing... If you are doing it for schema markup in Google SERPs all their examples show linking to the last part of the breadcrumb, see google rich snippets

If you want to inform users you can examine adding a text element for the last part but most just leave the last part as the page you are viewing.

I would set your GEO to USA as international is fairly untargeted and much of the people that typically use Google.com are US users, any of countries would typicallly use the local GEO domains.

You can set url.com and all the subdirectory locations seperately, i would consider setting url.com/US as a GEO of focused directory and then you can leave url.com as untargeted.
